Properties
1) High early strength and high strength properties
Its compressive strength can reach 35-50Mpa within 1 day, 50-70Mpa after 3 days, and it also can grows continually with the increasing of curing age.
2) High froze-resistance property:
If used at the temperature as low as 0-10,which early strength is 5-6 times than that of OPC; if used in 0-20 with little admixture, its strength in 3-7d can reach 70-80% of designed strength, with very little strength loss after 300 times of froze-thaw circle.
3) High impermeability: because of its dense structure, the impermeability of the concrete is 2-3 times than that of OPC in same grade.
4) Anti-carbonation property: it has good anti-carbonation property, and low dry-shrinkage
5) Corrosion-resistance: it has good corrosion-resistance quality, especially much better in seawater corrosion resistance than that of high anti-sulphate Portland cement, with more than 1 corrosion-resistance coefficient.

- Q:Is there any way to remove rubber cement stains? From clothes and carpet?
- Rubber cement may be a great tool as an adhesive, but when that adhesive turns into a stained mess on your fancy tablecloth or carpet it's not that great anymore. Removing unwanted rubber cement stains takes time and patience along with a few simple tools.
- Q:Hello All, I have had fixed dark brown tiles on my bathroom floor, however the guys did a bad job at it, and i can see the white cement in beween the tiles.. and its actually making the whole pattern look bad.. I was wondering if there was any way I could kind of colour the cement filling in between the tiles so that it blends with the colour of the tiles... ?Also any suggestions for removal of cement stains off these tiles? PLEASE Help, i am really in a mess here.
- There is a product which colors and seals at the same time. Sold in pint bottles. I used a q-tip to carefully paint it on only between the tiles. (remember this will seal it too...so take your time and put care into the application). Go to either Home Depot or Lowes. Look in tile department. It says it is to color grout. But, grout and the white cement (really called either thin set or mastic) is the basically same stuff and will color the same way.
- Q:cement effluents
- I okorder /. It is an extensive site. A search on cement effluents turned up over 3,500 results.
- Q:advisable storage method of cement?
- I know your friend and she (if I'm correct) is very much missinformed as to storage technique. As much as we both love her, (she's a fine lass) toss the advice. Your little friends need open air! There should be a small hook just under the hairline, on the neck, in the back...Find a comfy spot in the sun and hang 'em...they'll love you more for it.
- Q:Ok so I want to pour cement in this, im assuming, 12 by 8 ft sized area. How mane bags of cement would I need? How many boards do I need? Do I even need them? Do I also need that wire for the bottom? How much does that run?Can anyone give an estimate of the total cost?
- It sounds like you're building a patio or something? You need to build a form first. For something this size you'll want to rent a small concrete mixer. This link goes into the details...
- Q:Decrease in water/cement ratio will??1)increase in strength 2)Difficult to obtain a smooth finished surface3)Decrease in strength4)Reduction in long term durability Increase in water/cement ratio will??1)Increase in strength 2)Difficult to obtain a smooth finished surface3)Decrease in strength4)Reduction in long term durability
- It is sure that the strength of concrete is directly proportionate to the water cement ratio. Decrease in water cement ratio increase the strength of concrete to some extent, but an optimum ratio is to be maintened so that entire cement part of the concrete can take part in reaction, failing which the concrete will decrease its strength. More over for lesser W/C ratio the workability of the concrete will be affected. So that it is difficult to obtain finishing of your shape. on the contrary, if you increase the W/C ratio it will reduce the strength of concrete. As to react the chemical reaction of cement it required a optimum amount of water. More than that, residual quantity of water will be in the concrete structure. In due course that water will evaporate from the concrete leaving pores in the concrete surface. Which makes the concrete of lesser strength.
- Q:A bag of cement weighing 350 N hangs in equilibrium from three wires as suggested in the figure below. Two of the wires make angles θ1 = 61.0° and θ2 = 41.0° with the horizontal. Assuming the system is in equilibrium, find the tensions T1, T2, and T3 in the wires.T1 = T2 = T3 =
- The tension in the third wire is equal to the weight of the bag of cement. The sum of the vertical components of the tension in each of the other wires is equal to the tension in the third wire. So, the sum of the vertical components of the tension in each of the other wires is equal the weight of the bag of cement. Vertical component = T * sin θ For the left wire, vertical component = T1 * sin 61 For the right wire, vertical component = T2 * sin 41 Eq#1: T1 * sin 61 + T2 * sin 41 = 350 Since the system is in equilibrium, the magnitude of the horizontal components of the tension in each of the other wires is equal. Horizontal component = T * cos θ Eq#2: T1 * cos 61 = T2 * cos 41 T1 = T2 * cos 41/cos 61 Substitute (T2 * cos 41/cos 61) for T1 in Eq#1, and solve for T2. T2 * cos 41/cos 61 * sin 61 + T2 * sin 41 = 350 T2 * (cos 41/cos 61 * sin 61 + sin 41) = 350 T2 = 350 ÷ (cos 41/cos 61 * sin 61 + sin 41) = 173.4741944 N This is approximately 173.5 N Substitute 173.4741944 for T2 in Eq#1 and solve for T1. Eq#1: T1 * sin 61 + 173.4741944 * sin 41 = 350 T1 = (350 – 173.4741944 * sin 41) ÷ sin 61 = 270.0495844 N This is approximately 270 N. To check this answer, substitute both answers in Eq#2: T1 * cos 61 = T2 * cos 41 270 * cos 61 = 173.5 * cos 41 131 = 131 This proves that the tensions are correct! I hope that my work has helped you understand how to solve this type of problem.
- Q:I am trying to match a cement grout for stone patio to same color as my decomposed granite walkway color. I tried mixing grey cement with decomposed granite as aggregate in various ratios to make the grout (1:2, 1:3) but all are just grey. Would white portland cement (more $$$) work better or still be no match? I am afraid to try the cement color pigments cause I know I will never get it right. The decomposed granite is a light brownish color. They call it quot;orangequot; but that's probably because we are in central Texas and everyone near UT thinks everything is orange. Any help?
- The cement color works but a number of small trials are required to get it just correct. The trials need to be made with an adequate size so the components can be measured accurately and reproduced when the sample color is developed. Even after you think you have the correct color, try your proportions once more with a slightly larger sample to verify the correct ratio has been selected. As you are aware the wet color is different than the dried color. I would start with the cheaper cements and only go up in costs if you are not coming up with the color you want. You may want to try using mixtures of different sand colors if the granite is not getting you to the color you want. This definitely is a trial and error project. You may want to go slightly to the darker side of a match in that as the new grout weathers it will lighten slightly. After the grout weathers a very thin mix of cement and pigment can be mixed up and the joints can be painted with the blend. If bad goes to worse you may want to paint all the joints to make them consistent. I have used Liquid Cement Color by Quikrete which I got at Lowes, it was a bear but finally came up with an acceptable match.
- Q:We have very ugly cement floor for our outside space and want to change it up! We do not want to pour a whole new set of concrete however and we were wondering if we could use something to stick on top of our old concrete! :) We've heard mortar works...but we need direction plz help!!!!
- Frame it and then apply about 1 cement. You could even color the cement first. Embed the river stones so that you don't have to step into the concrete..parts at a time if it is a large space. In cold areas, use Don't expect this to last more than 5 years,
- Q:one that holds the best but not messy to work with
- You need to use Black Jack. It is messy, but that's what you need to seal the roof. Be careful when you work with it, and clean up immediately. Hope this helps.
